Here too,public universities charge more for out-of-state tuition.

That means that it's harder to make a market for it, so the dealer wants to charge more.
这意味着,这样的品种市场很小,所以中间商要收取更多的费用
So I prefer walking if I can, just because I feel more in charge.
所以如果可以,我更喜欢走路,因为我觉得那样我更能掌控自己。
And health care providers usually charge more. A World Health Organization survey of hospital and clinic births in nine Asian countries earlier this year found 27 percent were c-sections, and in China it was nearly half of all births.

So that means that the more stable molecule is going to be this molecule here, which actually puts the negative charge on be more electronegative atom.
因此这意味着更稳定的分子,应该是这一个,它真正把负的电荷放到了,电负性更高的原子上。
The Chronicle of Higher Education says at least fifty-eight private colleges now charge fifty thousand dollars or more a year.

Well, those hedge funds charge enormously more than what a standard manager of marketable securities' charges.
那些对冲基金经理的收费,远比证券投资经理的收费高
I walk as much as I can because I feel more in charge.
我尽量多走路,因为我觉得那样我更能掌控自己。
It turns out, and we're going to get the idea of shielding, so it's not going to actually +18 feel that full plus 18, but it'll feel a whole lot more than it will just feel in terms of a hydrogen atom where we only have a nuclear charge of one.
结果是我们会有,屏蔽的想法,所以它不会是完整的,但是它会比原子核电荷量,吸引力要大很多,只有1的氢原子的。
All right. So let's try one more example of drawing Lewis structures before we talk about formal charge.
好,让我们在讲形式电荷之前,再给一个例子画一下路易斯结构。
And shielding is a little bit of a misnomer because it's not actually that's the electron's blocking the charge from another electron, it's more like you're canceling out a positive attractive force with a negative repulsive force.
屏蔽有一点点用词不当,因为它事实上不是,电子阻挡了来自另一个电子的电荷,它更像你在用一个负排斥力,抵消一个正吸引力,但是屏蔽是考虑这个问题,的很好的方式。
So, if we compare the sulfur to the oxygen, the oxygen it turns out is more electronegative and that is what holds the negative charge in this molecule.
因此,如果我们来比一下硫和氧,氧应该有更高的电负性,而在这个分子中它确实有负的电荷。
So now we're done, actually there is one more step, which is to determine the formal charge.
那么我们现在做完了,实际上应该还有一步,那就是确定形式电荷。
